BOTTLE-CLOSU RE.

SPECIFICATION forming part of Letters Patent No. 693,161, dated February 11, 1902.

Application filed May 15, 1901.

To to whont it may concern:

Be it known that I, JOHN SoHIEs, residing at Anderson, in the county of Madison and State of Indiana, have made certain new and useful Improvements in Bottle-Closures, of which the following is a specification.

My invention is an improvement in closures for glass bottles and jars; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view, and Fig. 2 a longitudinal section, of a portion of a bottle embodying my invention. Fig. 3 is a sectional View similar to Fig. 2, but showing a somewhat different form of groove within the neck of the bottle. Fig. 4 is a top plan view of the cap shown in Figs. 1, 2, and 3. Fig. 5 isa detail sideview of the cap shown in Figs. 1 and at and supplied with a knob. Fig. 6 is a detail side View, partly broken away, of the wood liner; and Fig. 7 is a detail View of the cork strip used to provide the cushioning and sealing lining within the mouth of the bottle.

The bottle or jar A may in general respects be of ordinary design and has its neck B formed internally near its mouth with the cylindrical portion 0, which extends in practice about one-half inch from the mouth of the bottle and is provided adjacent to the bottle-mouth with a groove, which may be in the form of an undercut rabbet D, as shown in Fig. 2, or may be a more pronounced groove, as shown at E in Fig. 3. The upper end ot" the neck is preferably formed flat, as shown in Figs. 2 and 3, and may be widened laterally, as shown in said figures, to form a broad seat F for the gasket I and the flange of the cap, presently described.

\Vithin the mouth of the bottle I fit the sealing-strip, as shown in Figs. 2 and 3. The seal may be provided by a ring of wood 1 slit at 2 and provided 011 its inner side with threads or grooves at 3 for the threads on the cap and having on its outer side a rib at to enter the groove within the neck of the bottle. This rib 4: may be formed upon the seal in constructing the same or it may be produced by the expansion of the wood seal within the neck of the bottle under the influence of the Serial No. 60,335. (No model.)

moisture in the contents of the bottle. I show the wooden seal in detail in Fig. 6. It may be desired in some instances to make the seal from a strip of cork, such as shown in Fig. 7, of a suitable length, width, and thickness to operate as shown in Fig. 2, and to be bent upon itself in circular form to fit within the mouth of the bottle. When so fitted, the ends of the strip abut, and the resilience of the cork strip in a longitudinal direction aids in causing the same to bind within and fit tightly the neck of the bottle.

The cap H (shown in Figs. 1, 2, 3, and 4) is formed with a depending portion H, which may be slightly tapered to facilitate its entrance within the seal, and is provided with a thread H which begins slightly above the lower end of the stem portion H of the cap and terminates below the lateral circular flange H which rests upon the upper edge of the cork seal and the broad fiat end F of the bottle. In applying the parts, as shown in Figs. 2 and 3, the cap H has its stem portion H screwed into the seal. In doing this the threads will form their own way when the seal is of cork, operating to so compress the cork as to force it out into the groove formed within the neck of the bottle, and thereby increase the hold of the cork seal within the mouth of the bottle. It will also be seen that this compression of the cork seal out into the groove within the neck of the bottle tends to increase the tightness of the sealing-strip or the cork ring within the neck of the bott-le, and so aids in securing a better closure of the bottle, as is desired. A gasket 1, of rubber or other suitable material, is fitted around the depending portion H of the cap and extends thence outwardly over the inner seal and beyond the same to rest upon the lip of the bottle. By this means I secure a tight closure and avoid any exposure of the rubber gasket to the action of the contents of the bottle.

InFig. 5 the cap H is shown provided with a knob I, by which it may be turned, while in Figs. 1, 2, 3, and 4 the outer edge of the flange H is formed at H with corrugations by which it may be readily turned.

From the foregoing it will be noticed that the mouth of the bottle is formed internally with a groove to allow the seal to swell in and hold Within the mouth of the bottle, While the cap is held to the seal by the screW-th reads! It will also be understood that the threading of the cap into the ring, aswell as the moisture of the contents of the bottle, will operate to aid the natural resilience of the seal in forcing the same into the groove of the bottle-neck.

Having thus described my invention, What I claim, and desire to secure by Letters Patout, is-

A bottle or jar closure substantially as herein described, comprising the bottle having its neck provided at its upper end with an outwardly-extendinglip forming a broad flatsurface for the flange of the cap and the gasket, and having a groove within its neck near its tween the same and the flange of the cap, 0

substantially as set forth.
